Report #27336

[frontier] Swarm of 10\+ agents exceeding combined context limit with redundant system prompts

Implement hierarchical context distillation: shared immutable base context \(read-only\) \+ agent-specific deltas; use reference passing instead of full duplication.

Journey Context:
Multi-agent swarms replicate full context per agent, causing O\(n\) token growth. Hierarchical context sharing \(immutable shared prefix \+ mutable per-agent state\) reduces tokens by 70%. Alternative: message passing \(slower, stateless\). Winner for real-time collaborative agents \(coding swarms, design teams\) where 10\+ agents run concurrently.
